You see, it depends. As always, it's best to say "What's up?" to your doc. Generally, laser procedures won't affect the function of your device. Your eye doctor still may want to turn off the ICD during the procedure, just in case you were to move if it delivered a shock. You may want to consult with your cardiologist or EP before laser surgery, especially if a recommendation is made by your eye doctor about turning off therapy during surgery.
